[cc Wei Wang here] In the function reassign_device() in pci_amd_iommu.c, it seems pci_get_pdev_by_domain() fail to return a correct pci_dev. Here is the decode of IVRS table. It looks like 03:xx.x is behind a bridge 00:14.4 and uses this value as an alias ID. That might be a cause. From IVRS, I don't see anything wrong with 00:14.2 though. Maybe you can add more debug code to reassign_device(). -Wei 02 10 00 00 DEV=00:2.0 03 00 0f 00 04 01 0f 00 DEV=[0f:1.0, 0f:1.0] 02 18 00 00 DEV=00:2.0 02 00 0e 00 DEV=0e:0.0 02 20 00 00 DEV=00:4.0 02 00 0d 00 DEV=0d:0.0 02 28 00 00 DEV=00:5.0 02 00 0c 00 DEV=0c:0.0 02 30 00 00 DEV=00:6.0 02 00 0b 00 DEV=0b:0.0 02 48 00 00 DEV=00:9.0 02 00 0a 00 DEV=0a:0.0 02 50 00 00 DEV=00:a.0 02 00 08 00 00 00 00 00 DEV=08:0.0 43 08 09 00 00 00 09 00 04 ff 09 00 DEV=[09:1.0, 09:1f.7] 02 58 00 00 DEV=00:b.0 02 00 04 00 DEV=04:0.0 02 08 05 00 DEV=05:1.0 02 00 07 00 DEV=07:0.0 02 10 05 00 DEV=05:2.0 03 00 06 00 04 00 06 00 DEV=06:0.0 02 88 00 00 DEV=00:11.0 03 90 00 00 04 92 00 00 DEV=[00:12.0, 00:12.2] 03 98 00 00 04 9a 00 00 DEV=[00:13.0, 00:13.2] 02 a0 00 d7 DEV=00:14.0 02 a1 00 00 DEV=00:14.1 02 a2 00 00 DEV=00:14.2 02 a3 00 00 DEV=00:14.3 02 a4 00 00 DEV=00:14.4 43 00 03 00 00 a4 00 00 04 ff 03 00 DEV=[03:0.0, 03:1f.7] 02 a5 00 00 DEV=00:14.5 02 a8 00 00 DEV=00:16.0 02 a9 00 00 DEV=00:16.1 02 00 01 00 DEV=01:0.0 03 b0 00 00 04 b2 00 00 00 00 00 00 DEV=[00:16.0, 00:16.2] 48 00 00 d7 00 a0 00 02 48 00 00 00 07 01 00 01 -----Original Message----- From: Sander Eikelenboom [mailto:linux@xxxxxxxxxxxxxx] Sent: Tuesday, July 13, 2010 5:07 PM To: xen-devel@xxxxxxxxxxxxxxxxxxx Cc: Przywara, Andre; Joerg Roedel; Huang2, Wei; Konrad Rzeszutek Wilk; Jeremy Fitzhardinge Subject: MSI 890FXA-GD70: AMD IOMMU, VmError: Failed to assign device to IOMMU, (XEN) AMD_IOV: IO_PAGE_FALT: domain:10, device id:0x900, fault address:0x0 Hi All, I have bought a MSI 890FXA-GD70, and have been able to enable the IOMMU with a beta-bios from MSI. I succeed in passing through some pci-e devices to domU's (PV), but some other devices fail with both PV and HVM domains. The message is allways the same "Failed to assign device to IOMMU", with some added printk's the return code from "iommu.c/assign_device" seems to be ffffffed instead of the desired 0. Devices 00:14.2 and 03:06.* cause the domain(PV and HVM) to fail on creation with: Failed to assign device to IOMMU (BDF) Devices 09:01.* and 07:00.0 passthrough fine ( visible and working in pv domU). Since it's a beta bios, could it be the IVRS table supplied by the bios is not complete and therefore the iommu functions only for some devices ? With amd_iommu_debug it sometimes also prints an "IO_PAGE_FALT": (XEN) [VT-D]iommu.c:144: SEIK: assign_device: domain 14 (0:14.2)! (XEN) [VT-D]iommu.c:162: SEIK: assign_device rc: ffffffed !
